Mark, Jeremy Cutsforth-Gregory, Patrick Luetmer, Ajay A. Madhavan, Michael Oien, Paul Farnsworth, Girish Bathla, Steve Messina, Michael Link and Jamie Van GompelAmerican Journal of Neuroradiology October 2024, 45 (10) 1593-1596; DOI: https://doi.org/10.3174/ajnr.A8333
The purpose of this study was to use a validated brain MRI scoring system (Bern score) to evaluate patients with confirmed skull base CSF leaks for findings associated with SIH. The authors found that patients with skull base CSF leaks did not have brain MRI findings that are associated with SIH and likely have distinct pathophysiology from spinal CSF leaks.

This is an updated comprehensive review of the various myelographic techniques that can be used to identify CSF-venous fistulas. The authors discuss the advantages and disadvantages of each and describe provocative maneuvers that may improve the conspicuity of CVFs.

This study compared clinical outcomes in in-hospital strokes versus community-onset strokes in patients treated with endovascular thrombectomy for large-vessel occlusion. In-hospital strokes had overall faster time metrics from stroke onset to reperfusion. However, the rate of successful reperfusion and safety outcomes (in-hospital mortality and parenchymal hematoma) did not differ between the groups. Ninety-day mRS was also similar in both groups.
